Abstract: Application of numerical simulation software, consulting updip regional characteristics to bulid a typical geological model, use the method of seepage resistance to fracture well P1 in updip pinchout area. By comparing the development effect of fracturing well and the whole well group, determines fracturing technology in solving the updip pinchout area lacking for liquid has significant effect. On this basis, optimizes the angle between the fracture and the mainstream line and fracture half length, found that vertical cracks from the mainstream line, fracture half length of 85 meters, the development of fracturing effect is best.

摘要： 应用数值模拟软件CMG, 参照上倾区域的特点建立一个典型地质模型, 利用等渗流阻力法对位于上 倾尖灭区的油井P 1进行了压裂处理, 通过对比压裂前后压裂井及整个井组的开发效果, 确定压裂技术在解决上倾 尖灭区供液不足方面具有显著效果。在此基础上, 对裂缝与主流线之间的角度及裂缝半长进行了优化, 发现裂缝与 主流线垂直, 裂缝半长为8 5m时, 压裂开发效果最佳。
